Hello, First of all, I am sorry for my english. Then I am doing a application with CANBUS Protochol. so ı need to use PB13 pin of STM32F429. but when I use this pin, CAN2 is not work. When I look datasheet, this pin is connected VBUS. I set the pin to GPIO_AF9_CAN2, but This is not work still.  Can do you help me?

This has to be at least the fourth thread you've opened on this same topic, please don't do that..

It is not a chip level configuration problem, you need to address the current circuit already implemented on the board (STM32F429I-DISCO). ie remove parts or cut traces.

So have you looked at the circuit diagram or traced the wire to the components?
